Extractions: March 2001 features mice harboring a targeted disruption of the (7-dehydrocholesterol reductase) gene, located on mouse chromosome 7 (F5). The replacement targeting vector was designed to disrupt by insertion of the neomycin phosphotransferase gene and deletion of coding exons III, IV and part of exon V. Wassif et al. report that Dhcr7 (+/-) mice are viable and phenotypically indistinguishable from wild-type littermates. In contrast, Dhcr7 (-/-) mice mice display a marked reduction of serum and tissue cholesterol levels as well as a marked elevation of serum and tissue 7-dehydrocholesterol levels and provide a genetic mouse model of the human RSH/Smith-Lemli-Opitz Syndrome . Phenotypic similarities encompass intrauterine growth retardation, variable craniofacial abnormalities including cleft palate, poor feeding with an uncoordinated suck, hypotonia, decreased movement, and neurological deficits.

Extractions: August 2001 features mice harboring a targeted disruption of the (serine/threonine kinase 11, also known as ) gene, located on mouse chromosome 10. Ylikorkala et al. report that (+/-) mice are viable, fertile and phenotypically indistinguishable from wild-type littermates. In contrast, (-/-) embryos perish at midegstation and display a number of developmental abnormalities, including neural tube defects, increased mesenchymal cell death, and vascular anomalies. These alterations are associated with tissue-specific deregulation of VEGF (at E8.5 and E9.5), including abnormally elevated levels of VEGF in the mesenchyme, heart and yolk sac. Such observations position in the VEGF signaling pathway and suggest that the vascular abnormalities characterizing disruption are mediated at least in part by VEGF. Moreover, these findings provide a rationale for the increased risk of cancer incidence in

Professor Opitz is an eminent North American geneticist who did not favour the old system of naming syndromes after the doctor who first reports the condition. He named several conditions by representing the initials of the surnames of the first presenting families. However, a huge increase in the number of newly reported syndromes was one reason this system fell out of favour. The so-called type I and type II Opitz G/BBB syndromes appear the same but they may arise from different faults in one gene, or even from faults in quite different genes. This phenomenon is termed genetic heterogeneity and it is important for families because it complicates genetic risk prediction and makes gene testing more difficult. Probably, the autosomal dominant variety of Opitz G/BBB is commonest and in some families the gene fault or mutation is located on chromosome 22. In a few cases only, a chromosome 22q11-13 deletion has been diagnosed by a special (FISH) chromosome test.

Extractions: General Overview ... to detailed description Smith-Lemli-Opitz Syndrome... New Tests will Identify Rare Genetic Disorder Before Birth Scientists at the Foundation for Blood Research (FBR) are working to develop a way to prenatally detect a rare genetic disorder, without using invasive procedures such as analysis of the amniotic fluid through amniocentesis. The National Institute of Child Health and Human Development is funding this 3-year project. Researchers are focusing on Smith-Lemli-Opitz (SLO) syndrome, a serious inherited disorder occurring once in 20,000 births. Children with this syndrome are unable to make enough cholesterol to support normal growth and development, resulting in mental retardation and physical abnormalities. Wendy Craig, Ph.D., Senior Research Associate at FBR, coordinates the project. She says, "We now know that this syndrome is caused by the patient's inability to convert a certain chemical found in the blood into cholesterol. We have also discovered that blood tests routinely performed on pregnant women to screen for Down syndrome identify a substance that is lower if SLO is present. Using these findings, we have developed a model that will be tested on 1,000,000 pregnancies over the next several years." This project marks a significant step forward in researchers' ability to accurately identify rare genetic disorders through blood tests.

Extractions: Feasibility of Prenatal Screening for Smith-Lemli-Opitz Syndrome ... to general overview The Foundation for Blood Research has been awarded a grant from the National Institutes of Health to coordinate and evaluate data aimed at evaluating the efficacy of routinely identifying Smith-Lemli-Opitz Syndrome (SLOS) prenatally. This serious inherited metabolic disorder (birth prevalence 1:20,000) is characterized by moderate to severe mental retardation and congenital anomalies. Two circumstances now make it possible to carry out the proposed intervention trial. First, the cause of SLOS is now known to be a defect in the conversion of 7-dehydrocholesterol to cholesterol. This discovery makes it possible to confirm the diagnosis biochemically by measuring cholesterol precursors in the serum of affected individuals and in amniotic fluid. Secondly, the array of maternal serum analytes currently measured routinely to screen for Down syndrome in 2,000,000 U.S. pregnancies annually includes unconjugated estriol (uE3). This analyte requires cholesterol as a precursor, and its concentration in maternal serum is lower when the fetus has SLOS. The major barrier to identifying SLOS prenatally is the absence of sound screening methodology that takes into account the detection rate, the false positive rate, and the prevalence. We have developed a model based on actual data from SLOS pregnancies, and propose to test it in 1,000,000 pregnancies in which maternal serum uE3 is being measured along with other analytes, as part of routine screening for Down syndrome.
